2. INTRODUCTION
• ABB Limited has been selected by Power grid
Corporation of India Ltd. to deliver the world’s
first multi-terminal UHVDC transmission link,
worth $ 900 million.
• The link is called the 800 kV, 6,000 MW HVDC
Multi Terminal NER/ER - NR/WR Interconnector
– I Project (NEA800 in short and also known as
North East - Agra HVDC).
4. CONTD.....
The link comprises four terminals located at three
converter stations with a 33% continuous
overload rating and the power transmission
system will thus have the possibility to convert
8,000 MW – which is the largest HVDC
transmission ever built.
ABB will execute the project together with its
partner Bharat Heavy Electricals Ltd. (BHEL),
who will deliver the remainder of the contract,
which is worth more than $1.1 billion in total.
5. CONTD.....
The partners have the responsibility for
execution, including system engineering, design,
supply and installation of three HVDC converter
stations. The first stage of the system is scheduled
to be operational in 2014 and the second stage in
2015.
The North Eastern region of India has hydro
power resources,approx.65,000 MW. The
resources are scattered over a large area, whereas
load centres are several even thousands of
kilometres away.
6. CONTD....
India plans to create power pooling points in the
North-Eastern region, to collect power from
several hydro power stations and to transport it on
800 kV DC bipolar lines to major load centres.
The first pooling point (= converter station) of the
first Indian 800 kV HVDC link will be located at
Biswanath Chariali in the state of Assam in North
Eastern region, while the second converter station
will be located near Alipurduar in the state of
West Bengal in Eastern region.
